Kingspan U-Value Calculator
Understanding the thermal performance of your building’s envelope is crucial for energy efficiency and comfort. The Kingspan U-Value Calculator is a free, interactive tool designed to help architects, builders, and homeowners calculate the U-Value of Kingspan insulation products.
- Select the insulation material from the dropdown menu.
- Enter the thickness of the insulation in millimeters.
- Click the ‘Calculate’ button to see the U-Value and a visual representation of the insulation’s performance.
The U-Value, or thermal transmittance, is a measure of the rate of heat transfer through a material or assembly. It is expressed in units of W/m²K. The formula used in this calculator is based on ISO 10211:2017 and takes into account the thermal conductivity of the material and its thickness.
Real-World Examples
Let’s explore three case studies to illustrate the use of this calculator:
Data & Statistics
| Material | Thermal Conductivity |
|---|---|
| PUR | 0.024 |
| PIR | 0.022 |
| XPS | 0.035 |
| Material | Thickness (mm) | U-Value (W/m²K) |
|---|---|---|
| PUR | 50 | 0.00048 |
| PIR | 75 | 0.00030 |
| XPS | 100 | 0.00035 |
Expert Tips
- Consider the overall U-Value of the building envelope, not just individual components.
- Inspect the insulation and air barrier continuity during installation.
- Regularly maintain and inspect the insulation to ensure its performance over time.
- For walls, use a combination of insulation types to achieve the desired U-Value.
- For roofs, consider the pitch and orientation when selecting insulation.
- For floors, insulate both the top and bottom to maximize energy efficiency.
Frequently Asked Questions
What is the U-Value?
The U-Value, or thermal transmittance, is a measure of the rate of heat transfer through a material or assembly. It is expressed in units of W/m²K.
How does this calculator work?
This calculator uses the thermal conductivity of the selected material and its thickness to calculate the U-Value according to ISO 10211:2017.
